Expanding PC sales in emerging market is increasing the rate of software piracy, according to a recent study by industry watchers. The rate of global software piracy in 2009 was 43%, meaning that for every $100 worth of legitimate software sold in 2009, an additional $75 worth of unlicensed software also made its way into the market, according to a recent study by the Business Software Alliance (BSA) and IDC.

This is a 2-percentage-point increase from 2008, and is fueled largely by expanding PC sales in emerging markets, the study found.

Software theft exceeded $51 billion in commercial value in 2009, according to the BSA. IDC says lowering software piracy by just 10 percentage points during the next four years would create nearly 500,000 new jobs and pump $140 billion into "ailing economies."

Despite the uptick, 2009 piracy rates are better than expected, according to BSA. Still, "Few if any industries could withstand the theft of $51 billion worth of their products," said BSA President and CEO Robert Holleyman, in a statement.

In the United States, software piracy remained at 20%, the lowest level of software theft of any nation in the world. However, given the size of the PC market, the commercial value of pirated software in the United States was $8.4 billion in 2009, the groups said.

Other findings of the BSA/IDC study were:

Piracy rates increased in 19 global economies, up from 16 in 2008

The factors driving up the global piracy rate include growth in the consumer PC base and in emerging markets — both segments with high piracy rates
